Fluid Steering TRIZ Cases

Independent electric steering pumps vary speed with steering state to cut soil compactor energy use while preserving emergency steering.

A Lugre-model feedforward term compensates steering friction hysteresis to cut reverse delay and improve pinion position tracking.

Bolt holes spaced away from tooth roots help this ground-engaging track master link reduce stress concentration, rocking, and fracture.

A rigid-flexible hydraulic pipe layout lets a swing axle move while preventing supply pipe interference near the axle case.

A pivoting rear steering assembly and independent drive wheels improve buggy stability, control, and precise dumping in confined spaces.

Starter cranking restores the engine-driven hydraulic pump after an unintended shutdown, preserving steering assist while limiting starter load.

A common steering housing integrates the torque sensor, pump, and transmission to cut piping, save space, and reduce hydraulic losses.

Independent transverse control arms let each crane wheel move separately, cutting axle space use while preserving ground clearance and adaptability.

External isolating mechanisms move steering angle sensors outside hydraulic cylinders, cutting repair time, downtime, and replacement cost.

Automatic valve control locks trailer self-steering wheels in reverse and unlocks them in forward travel to reduce damage, stress, and tire wear.

Acceleration-based torque thresholds separate driver steering input from travel-induced torque, reducing false positives in autonomous driving handover.

GPS-guided paint carriage control aligns dispensing nozzles to existing roadway mark paths, reducing manual labor and worker exposure.

Filtered GPS and machine vision guide a laterally movable paint carriage to replicate roadway mark paths with safer, more uniform application.

Waste heat from the steering drive is transferred through a heat exchanger to keep hydraulic oil warm during power-on-demand operation.

Compressed air nozzles replace vacuum suction so a wall-climbing drone can move on rough or hollow vertical surfaces with lower power use.

Pump speed follows the higher of steering input or lever deflection, cutting electric energy use while preserving hydraulic flow for steering and work functions.

Drive waste heat is transferred into hydraulic oil to keep electrohydraulic steering ready without continuous fluid circulation.

An auxiliary flow path lets a measuring motor support equal emergency steering in both directions while absorbing pressure shocks.

Compares actual and nominal steering response parameters to detect hydraulic power steering degradation early and prevent servo loss.

Standardized steering modules let commercial vehicles match load and space constraints through interchangeable actuators, pumps, motors, and controls.

A clutch-switched dual-pump layout keeps hydraulic steering assist available when the engine is off while avoiding unnecessary energy use.

A pressure-triggered second pump helps a work vehicle maintain oil flow and 18.5 bar pressure for steering and driveline demand.

Pre-pressure generation and a shut-off valve keep electrohydraulic steering ready while cutting energy use from continuous pump operation.

Parallel propulsion- and wheel-driven pumps keep steering fluid flow steady, reducing feedback disturbances while improving safety and efficiency.

Parallel controllable and wheel-driven pumps maintain steering fluid flow through source transitions, reducing feedback and energy use.

A threaded valve and motor housing interface enables 360° motor orientation, cutting valve housing variants, tooling cost, and assembly complexity.

Branch-connected hydraulic conduits with flow control preserve steering after hose failure, reducing complexity and cost while meeting safety needs.

Separate branch conduits with flow-influencing elements keep hydraulic steering functional after hose failure without duplicating steering units.

Switchable dual dosing devices and solenoid valves let hydrostatic steering balance fast low-speed maneuvering with stable road handling.

Cross-over control blends open and closed loop steering to reduce drift, backlash effects, and abrupt response changes.

Pneumatic pressurization keeps the disabled hydraulic steering circuit pressurized, cutting energy use while limiting pressure-peak damage.

A pre-charged hydraulic accumulator supplies initial steering flow while threshold-based pump activation reduces electricity use without delayed response.

A closed hydraulic circuit uses check valves and an accumulator to maintain steering pressure without a booster pump.

A hydrostatic steering assembly uses two independent motors to maintain torque assistance and manual steering continuity during failures.
